Colt Le6920 Replacement Barrel Stripped 16.1In

The Colt LE6920 replacement barrel stripped is the factory-spec barrel solution for LE6920 owners ready to refresh a worn-out bore or builders committed to genuine Colt components. This 16-inch stripped barrel gives you the core element that makes the LE6920 platform reliable—the same barrel profile and rifling Colt installs on its factory rifles, without the extras you may not need.

Built with six-groove rifling and a 1:7-inch twist rate, this barrel handles the full spectrum of 5.56 NATO and .223 Remington loads with consistent accuracy. The M4-style feed ramps ensure smooth round feeding in combat-profile use, whether you're running suppressors, precision loads, or high-volume range sessions. Chrome lining inside the bore resists corrosion from moisture and powder residue, extending barrel life in field conditions or between deep cleans.

The barrel is chambered for a carbine-length gas system and ships with the barrel extension already installed, so you're ready to index it onto a bolt carrier group and gas tube. The muzzle is threaded 1/2"-28 TPI—the standard for AR-15 suppressors, flash hiders, and muzzle devices. If you need more than the barrel alone—barrel nut, front-sight tower, or a complete assembly—Colt offers those versions separately, giving you flexibility to build to spec or swap into an existing rifle.

Specifications

Frequently Asked Questions

Will this barrel fit my Colt LE6920?

Yes. This is the factory replacement barrel for the LE6920 platform, manufactured to Colt's original specifications. It uses the same profile, extension, and gas system configuration as the original LE6920 barrel.

Is the barrel extension included?

Yes. This stripped barrel comes with the barrel extension already installed. You will need to source a barrel nut and gas tube separately if you're doing a complete swap from a donor rifle.

What ammunition does this barrel stabilize?

The 1:7-inch twist rate is optimized for standard 5.56 NATO and .223 Remington ammunition across typical field and range weights. It will stabilize heavier match loads as well.

Can I add a suppressor to this barrel?

Yes. The muzzle is threaded 1/2"-28 TPI, the standard AR-15 threading that accepts most suppressors, flash hiders, and muzzle brakes designed for 5.56 platforms.
